Function Documentation

void ReadTIFFImage	(	InputParameters *	p_Inp,
		VideoDataFile *	input_file,
		int	FrameNoInFile,
		FrameFormat *	source,
		unsigned char *	buf
	)

Reads entire tiff file from harddrive. Any processing is done in memory, reducing I/O processing.

Parameters:

	p_Inp	Input configuration parameters
	input_file	Input file to read from
	FrameNoInFile	Frame number in the source file
	source	source file (on disk) information
	buf	memory buffer
